Mogul tractors were produced by the International Harvester Company (IHC).
IHC was formed in 1902 by the merger of the McCormick Harvesting Machine Company and Deering Harvester Company.
Two lines of tractors were produced by the IHC:
The Mogul series produced in Chicago (where McCormick had been made). These were sold by the McCormick dealer network.
b) The Titan series produced in Milwaukee (where the former Deering products
had been made.) Titans were sold by the Deering network dealers.
Both lines were similar but were marketed separately. Their development rose from the fact that demand for large tractors used to break up virgin
prairie land fell off in the mid-teens. Before that McCormick was noted for its giant 45hp Mogul. This was because the land boom in western Canada collapsed and therefor the sales of the larger tractors, which had been produced before, fell off rapidly to
coincide with that. This stimulated manufactures to come up with light weight tractors (2-3 plough) to replace horses on smaller farms.
